I came across this filament from a company called Polymaker called PolyFlex. This is what their website says:
One of our main goals when developing PolyFlex™ was to make it easy for everyone to use. Flexible filaments are known to be difficult to work with. Well, not any more. PolyFlex™ is designed to be compatible with almost all desktop FDM/FFF printers and requires no hardware modification. Not only does it print smoothly, but also adheres well to a large variety of surfaces with no need for a heated build platform, leaving you to think about nothing other than what model you are going to print.
I really want to be able to print flexible filament but haven’t been able to justify the cost of a Flexystruder. I’m wondering if this filament is a good alternative. Has anyone tried it?
